Carefree Arizona USA Horizontal Dial 1
A 90 ft. diameter horizontal dial with a large reflecting pool beneath the gnomon designed by John Yellott. The hour markers are 4 ft. diameter concrete circles. The dial is designed to show solar time corrected for the time zone offset. Thus the hour markers have been moved ahead of the solar time position. The hour lines are separated by alternating dark and light colored stones. The gnomon itself is 4 ft. wide, 62 ft. long and the tip is 35 ft. high. A pilot dial at a scale of 1/4 in. =1ft. is at the South end of the large dial. It is constructed of gold-anodized aluminum with time lines at 10 minute intervals. An equation of time plaque is nearby. The upper surface of the dial formerly served as a solar water heater to provide hot water to the city's first office building. Numerals face outward, so that they are more easily read by viewers.

Flagstaff Arizona USA Horizontal Dial 2
Small horizontal dial on carved pedestal. It was a gift from the observatory staff to Dr. Lowell.

It shall be inscribed with all your names and set up on the top of Mars Hill." A square stone base supports a tapering cylindrical column. At the top is a square plinth supporting the small horizontal dial. As of March 1996, the dial has resided inside the observatory building.
